2k2 cocker, 2k2 all american barrel, 12v revvy, nitro, not much else....

Strengths:

Fast...just really fast.
Quiet, really cool design that looks great. Heavy but well balanced. Cool features like a little bead thing that prevents it from rotating when paint is gone. Pretty quiet...just the nicest hopper you can get, no more chops.

Weaknesses:

I think it may have broken a paintball inside the hopper and it seems hard to clean. Tries to feed sometimes even when it doesn't need to. Can't use black paint I hear. Expensive....really expensive.

Conclusion:

Best hopper you can buy. If you have an electro you'll really want this thing. No more worrying about firing too fast, cause I have outfed my revvy before. I wouldn't be worried about chopping when firing this.
